Calif. border agents find pot encased in concrete

San Diego 
Border Patrol officers found nearly 400 pounds of marijuana encased in concrete on the back of a truck at a San Diego-area crossing.

U.S. Customs and Border Protection said in a statement Monday that a dog at the Otay Mesa crossing's cargo facility alerted officers that the shipment of concrete barriers in the back of a tractor-trailer driven by a 59-year-old Mexican citizen on Friday could contain drugs.

Officers drilled a hole in one of the barriers and found what turned out to be marijuana. Continued searching revealed 77 wrapped packages totaling 384 pounds of marijuana with a street value of more than $230,000.

The truck was seized and the driver, whose name has not been released, was arrested and taken to the federal Metropolitan Correctional Center in San Diego.
